I don't see a "Light" Patch anywhere
Neither do I. In fact I can't find any S10 Updates on this new Forum. I gave-up a long time-ago, trying to Fathom it out.It was so easy on the old Forum. Maybe someone-else can direct you?
In the meantime, go to: www.romskye.com You should find S10.7 "Light" & "Full" Patches there.
I've seen another recent Post re: "Catastrophic Failure", but can't find that, doing a Search. I think it may be rfelated to left-over Registry entries from Pinnacles InstantDVD Recorder. Unfortumately you can't use Pinnacle's RegDelete, 'cos you've done a "Repair", rather than a "Reinstall".
If you didn't do a "Custom" rather than a "Typical Install", when you 1st Installed S10, you will have Installed InstantDVD. Check ADD/REM PROGs & Remove it. Also Remove Pinnacle's Mediamanager/Server. You don't need it & it's a PC "resource-hog", before you Update to S10.7
Good luck
